Le Chatelier (Haber)
The Haber equilibrium N₂ + 3H₂ ⇌ 2NH₃. Disturb it and watch it shift back (Le Chatelier).
Open the interactive simulation →How to use this simulation
- Press play and let the mixture settle.
- Use the “Disturb” panel: change temperature or pressure, or add/remove N₂, H₂ or NH₃.
- Watch the NH₃ percentage and read “What happened”.
What to notice
- Higher pressure favours the side with fewer gas molecules (NH₃).
- The reaction is exothermic, so higher temperature lowers the NH₃ yield.
- Only temperature changes the value of K.
Try this
Remove NH₃. Which way does the equilibrium shift, and does K change?
